    sildenafil

    Advertisements



    A 32 y/o female patient on continuous oxygen via nasal cannula presents to the pharmacy window with a prescription for sildenafil [ViagraŽ]. She seems fatigued and exhibits dyspnea after walking the short distance across the lobby from the internal medicine clinic to the pharmacy window.

    Do you reject the prescription immediately, espousing the current Health Affairs policy stating the drug is used for males > 18 years of age for erectile dysfunction of specified causes?

    Maybe not. If the patient has pulmonary hypertension (based on observed symptoms and chronic oxygen therapy), she MAY be a candidate for this drug. Obviously, there would need to be a precise diagnosis of this disease before considering this drug therapy. Consultation with the prescribing/attending physician would be in order.

    Interesting, I did not know that Viagra can be use for pulmonary hypertension. One stone kills two birds. I better get some.

    This is confusing! I just recently heard from a Kaplan live course that Viagra does not work for women. Can somebody look this one up for me and correct this matter once and for all?

    re

    Erectyle dysfunction is the most common indication for sildenafil but not the only one anymore. "Recently, researchers learned that a drug widely used for impotence, sildenafil (Viagra), may also be effective as a selective vasodilator of the pulmonary system. Sildenafil is an inhibitor of PDE 5, a hormone produced by the body that causes blood vessel to constrict. Researchers believe that because of the high concentrations of PDE 5 in the lungs, sildenafil may function in a similar manner to nitric oxide or iloprost".
    So in this case this drug is being prescribed for pulmonary hypertension.I think in Kaplan when they say "it doesnt work for women" they are exclusively talking about sexual dysfunctions and not about pulmonary hypertension .
    hope this helps.
